GOLD MEDAL ABS

Nine serious ab moves from top Olympic trainers that will score you a rock-solid middleTED SPIKER

Train your core with these eight moves (and one bonus move) three nonconsecutive days a week. Either do them all together as a stand-alone workout or add three or four of them to the end of your usual strength-training routine.

For each move, start with one set. Once you can complete all the reps with perfect form, add another.
